Modular jar

ABSTRACT

The present invention relates to a modular jar having sections that may be selectively removed as contents are emptied. A base section includes a floor and a sidewall upwardly extending therefrom. The sidewall defines an open top at an upper end and includes an upper fastener. An extension section includes a sidewall that defines an open interior space and includes upper and lower ends. The extension section includes an upper fastener at the upper end and a lower fastener at the lower end. All upper fasteners have a configuration that is complementary to a configuration of all lower fasteners such that the extension section may be coupled to the base section or to another extension section. The modular jar includes a lid that may be removably coupled to an upper end of an extension section. The upper and lower fasteners may include complementary threads or twist lock elements.

BACKGROUND OF THE INVENTION

This invention relates generally to containers and, more particularly, to modular jars that may be coupled together to form ajar of variable height. As contents from the combined jars are removed, the jars may be easily separated so that all of the contents therein may be conveniently removed.

Contents from the bottom of a storage container are often difficult to remove in that the sides of the container are too close together to enable a person to conveniently reach to the bottom. In such cases, the container must be tipped or even completely turned upside down to remove the final items. This action often results in the final items being unexpectedly or undesirably removed all at once.

Various containers for removing final items in a more controlled manner have been proposed in the art. Although assumably effective for their intended uses, the existing devices do not provide for a variable size container giving easy access to remaining items without the need for tipping or inversion of the container.

Therefore, it would be desirable to have a modular jar having a variable height and having sections that may be selectively removed as the contents are emptied so that all of the contents may be easily removed. Further, it would be desirable to have a modular jar having a base section, removable extension sections, and a lid that may be combined or removed as needed.

SUMMARY OF THE INVENTION

Accordingly, a modular jar according to the present invention includes a base section having a floor with a sidewall extending upwardly therefrom. The sidewall defines an open top with an upper fastener such that the base section defines an interior space in which to hold selected items, such as food items.

The modular jar also includes an extension section having a continuous side wall having upper and lower ends and defining an open space therebetween. The extension section includes an upper fastener at the upper and end and a lower fastener at the lower end. All of the upper fasteners have configurations that are complementary to configurations of all lower fasteners such that a lower section may be releasably coupled to the base section or to another extension section. The fasteners may be, for example, a twist lock or threads.

Therefore, a general object of this invention is to provide a modular jar having multiple sections that may be coupled together to hold items therein.

Another object of this invention is to provide a modular jar, as aforesaid, in which extension sections may be selectively removed as contents are removed so as to give convenient access to all items stored therein.

Yet another object of this invention is to provide a modular jar, as aforesaid, in which removal of jar sections is quick, easy, and user-friendly.

Still another object of this invention is to provide a modular jar, as aforesaid, that is easy and economical to manufacture.

Other objects and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, embodiments of this invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

A modular jar 100 according to the present invention will now be described in detail with reference to FIGS. 1 a through 4 d of the accompanying drawings. More particularly, a modular jar 100 according to the current invention includes a base section 110, an extension section 120, and a lid 130.

The base section 110 has a sidewall 112 that extends generally upwardly from a floor 111. As best shown in FIGS. 2 and 4 c, the base section sidewall 112 presents upper and lower ends 112 a, 112 b and defines an interior open area 115 therebetween. The upper end 112 a of the base section sidewall 112 includes an upper fastener 150 which may be, for example, threads 150 a (FIGS. 1 a, 2, and 4 d) or twist lock elements 150 b (FIG. 3). While the threads 150 a are shown as external threads, they may alternately be internal threads.

The extension section 120 includes a sidewall 122 that presents upper and lower ends 122 a, 122 b and defines an interior open area 125 therebetween. The upper end 122 a of the extension section sidewall 122 has another upper fastener 150 which may be, for example, threads 150 a (FIGS. 1 a, 2, and 4 d) or twist lock elements 150 b (FIG. 3) as described above. The lower end 122 b of the extension section sidewall 122 has a lower fastener 155 which may be, for example, threads 155 a (FIGS. 1 a, 2, and 4 d) or twist lock elements. All of the upper fasteners 150 are respectively complementary to all of the lower fasteners 155. In other words, if the upper fasteners 150 are external threads 150 a, for example, then the lower fasteners 155 are complementary internal threads 155 a.

The lid 130 is sized to selectively cover the base section 110 and the extension section 120, respectively, and has a lower fastener 155. The lower fastener 155 may be, for example, threads 155 a (FIGS. 2, and 4 d) or twist lock elements as described above.

As shown throughout the drawings, the base section sidewall 112 may be a generally cylindrical shell and the extension section sidewall 122 may be a generally cylindrical shell that has a diameter substantially equal to a diameter of the generally cylindrical shell of the base section 110. Alternately, the base section sidewall 112 and/or the extension section sidewall 122 may respectively be rectangular, hexagonal, octagonal, or another regularly or irregularly shaped shell.

FIG. 4 d shows that a seal 140 may be situated at the upper end 112 a of the base section sidewall 112 to selectively seal the base section 110 to the extension section 120 and the lid 130, respectively, as described below. Though the seal 140 in FIG. 4 d is an o-ring, other types of seals may alternately or additionally be used.

In use, the extension section 120 may be coupled to the base section 110 by mating the upper fastener 150 of the base section 110 with the lower fastener 155 of the extension section 120 (FIGS. 1 b and 1 b through 4 d). In other words, the base section threads 150 a may be coupled with the extension section threads 155 a or the twist lock elements 150 b of the base section 110 may be coupled with the twist lock elements of the extension section 120. When the extension section lower fastener 155 is coupled to the base section upper fastener 150, the base section open area 115 and the extension section open area 125 may define a continuous open area, as shown in FIG. 4 c. The seal 140 may aid in making the connection between the base section 110 and the extension section 120 air-tight and/or water-tight. The lid 130 may be coupled to the extension section 120 (FIGS. 1 b, 4 b, and 4 c) by mating the upper fastener 150 of the extension section 120 with the lower fastener 155 of the lid 130. In other words, the extension section threads 150 a may be coupled with the lid threads 155 a or the twist lock elements 150 b of the extension section 120 may be coupled with the twist lock elements of the lid 130. Though only one extension section 120 is shown throughout the drawings, two or more extension sections may be coupled together to form a larger composite extension section 120.

The lid 130 may be selectively separated from the extension section 120 (i.e., by uncoupling the upper and lower fasteners 150, 155) to access contents in the extension section open area 125 and the base section open area 115. Once the contents of the extension section open area 125 have been removed, the extension section 120 may be separated from the base section 110 (i.e., by uncoupling the upper and lower fasteners 150, 155). The contents of the base section open area 115 may be more easily accessed after the extension section 120 is removed. To cover the base section open area 115 after the extension section 120 has been removed, the lid 130 may be coupled to the base section 110 (FIG. 3). More particularly, the upper fastener 150 of the base section 110 may be coupled with the lower fastener 155 of the lid 130 as generally discussed above.
